Hi

TNX bro i could find the my problem , my problem was about these section *foreach (my $word = <$inwp>) { $countp{$word}++ ; }* , *foreach (my $word = <$nwt>) {$countn{$word}++ ; }* because i split the words by /\n/ that my code didn't need to this separator

my new code

You appear to be just counting the words in the words file Positive2.txt and I can't see where you are spitting the sentences in Positive.txt into words.

Perhaps this will help you progess

#!/usr/bin/perl
use strict;

# create positive word hash
my $pos_words = '/root/Positive2.txt'; 
open my $fh_in,'<:encoding(utf8)',$pos_words
     or die "Could not open $pos_words : $!";
my %pos_word = map { s/^\s+|\s+$//g; $_=>1  } <$fh_in>;
close $fh_in;

# open positive word count output file     
my $pos_outfile = '/root/wordsbagp.txt';
open my $fh_out,'>',$pos_outfile
     or die "Could not open $pos_outfile\n";

# read positive sentence file
my $pos_text = '/root/Positive.txt';
open my $fh_in,'<:encoding(utf8)',$pos_text
     or die "Could not open $pos_text : $!";
my @train = <$fh_in>;
close $fh_in;

# split into 2 arrays 70% / 30%
my $offset = int 0.7 * @train;
push my @test, splice @train,$offset;
my $lineno = 0;

for my $line (@train){
  ++$lineno;
  # split sentence into words
  chomp($line);
  my @words = split /\b/,$line;
  
  # count positive words only
  my %count = ();
  for my $word (@words){
    ++$count{$word} if exists $pos_word{$word};
  }
  
  # print results
  print $fh_out "\nline $lineno: $line\n";
  for my $word (sort keys %count){
    printf $fh_out "  %-10s => %d\n",$word,$count{$word};
  }
};
close $fh_in;
close $fh_out;
